Teb ceev: HCF yog Deployable, tab sis lub interface yuav tsum tsim nyog
Hollow core fiber tau pom tias qis tshaj tawm latency thiab, nyob rau hauv cov kev tshawb fawb fibers xaiv, attenuation hauv qab no qhov zoo tshaj plaws qhia cov khoom -core silica tshwm sim.Cov txiaj ntsig no tsis ua rau cov khoom siv sib txuas, sib txuas thiab cov kev xav tau hloov mus rau txhua qhov txuas HCF.
Rau tus tsav, cais peb lo lus nug: yuav ua li cas HCF ntu txuas rau ib leeg, HCF hloov mus rau tus qauv li cas - hom fiber ntau, thiab yuav ua li cas cov kev sib dhos tiav yog txuas thiab sim. Yuav tsum tau ntsuas qhov kev poob qis, rov qab poob, kawg - lub ntsej muag cov qauv, lub zog ntawm txhua qhov sib txuas thiab kev sib txuas bidirectional - cov ntaub ntawv pov thawj rau cov qauv fiber ntau raug yuav.
1. Cov pov thawj HCF tam sim no ua pov thawj li cas-thiab Nws Tsis Yog
Thaum Lub Rau Hli 2026, Tuam Tshoj Telecom, YOFC thiab Dekoli tau tshaj tawm qhov kev sim ua haujlwm nqa 1.2 Tb / s ib lub voj voog thiab 51.3 Tb / s aggregate muaj peev xwm tshaj 206.5 km unrepeatered HCF ncua. Lub kaw lus siv EDFA amplification yam tsis muaj teeb liab nruab nrab rov tsim dua lossis tej thaj chaw deb -pumped amplification. Cov no yog cov neeg koom nrog- tau tshaj tawm cov txiaj ntsig los ntawm ib qho kev sib txuas tshwj xeeb thiab kev tsim qauv, tsis yog cov lus qhia dav dav rau txhua HCF cable lossis kev sib dhos tsis sib haum.

Sau txhua HCF-rau-HCF splice, HCF-rau-SMF kev hloov pauv thiab cov khub sib txuas sib txuas. Sau cov qauv tsim fiber ntau thiab cov khoom muag ntawm txhua qhov chaw; "LC" lossis "SC" ib leeg tsis yog cov lus hais txog kev sib haum xeeb.
Splicing muaj peev xwm
Paub meej tias daim ntawv thov splicer, tuav, cleaver thiab arc daim ntawv qhia tau raug siv rau HCF yuav. Yuav tsum tau ua piv txwv cov txiaj ntsig thiab txhua yam - pov thawj muaj zog es tsis yog kev vam khom rau cov txheej txheem SMF.
Xeem muaj peev xwm
HCF backscatter tuaj yeem sib txawv raws qhov txuas, yog li ib qho piv txwv - txoj kev OTDR cov kev xav tuaj yeem ua rau qhov kev tshwm sim yuam kev. Paub meej tias kev tau txais ob txoj kev, kev sib koom ua ke thiab HCF-cov ntawv tshwj xeeb- ua tiav.
Kev tshuaj xyuas thiab kev ruaj ntseg fais fab
Xam lub hwj chim kho qhov muag ntawm txhua qhov nkag tau siv tau. Txhais kev tshuaj xyuas, tu, lub zog- tawm thiab sau ntawv- khaws cov txheej txheem ua ntej kev teeb tsa, tshwj xeeb tshaj yog qhov twg lub zog hauv cheeb tsam tshaj lub koom haum tau tsim siab - lub zog pib.
5. Splicing, kuaj thiab txais
Siv ib qho kev faib tawm, tsis yog ib qho universal splice - tus lej poob
Ib qho pheej rov ua dua 0.16 dB tus nqi los ntawm 2013 HCF photonic-bandgap-fiber-rau- nws tus kheej sim. Nws yuav tsum tsis txhob muab nthuav tawm raws li qhov nruab nrab tam sim no rau tag nrho HCF. Hauv 2025 10,714 km recirculating{10}}loop sim, cov kws sau ntawv tau tshaj tawm cov splice ib txwm{11}}vim kev poob ntawm 0.05–0.15 dB rau cov kev xaiv DNANF spans.
